Photovoltaic panels convert sunlight, a renewable energy source, into electrical energy. The abundant irradiance will heat the photovoltaic panel, reducing the panel's efficiency. This study proposes using PCM 36 as a cooling technique to reduce the temperature of the photovoltaic panel, which is low-cost and has higher latent heat capacity. The indoor solar simulator study is performed to meet the IEC 60904-9 standard. The research process starts with validating PCM 36, sun simulator testing, validating the photovoltaic panel, and fabricating a container to place the PCM 36 at the rear side of the photovoltaic panel to cool down the temperature. The final experiments are conducted indoors, using three different irradiance levels and a one-hour photovoltaic panel operation under the sun simulator. The optimal results reveal a 31.67% reduction in temperature and a 6.83% increase in electrical efficiency at a maximum of 40 minutes, 500 W/m2 irradiance, with a 9 mm thickness of PCM 36. Throughout this study, the efficiency of the photovoltaic system is enhanced by effectively reducing the temperature within the optimal range by incorporating phase change material.

In order to explore the wind load characteristics acting on solar photovoltaic panels under extreme severe weather conditions, based on the Shear Stress Transport (SST) κ-ω turbulence model, numerical calculations of three-dimensional incompressible viscous steady flow were performed for four installation angles and two extreme wind directions of the solar photovoltaic panels. The wind load characteristics on both sides of the photovoltaic panels were obtained, and the vortex structure characteristics were analyzed using the Q criterion. The results indicate that, under different installation angles, the windward side pressure of the solar photovoltaic panel is generally higher than the leeward side. The leeward side is prone to forming larger vortices, increasing the fatigue and damage risk of the material, which significantly impacts the solar photovoltaic panel. As the installation angle increases, the windward side pressure of the solar photovoltaic panel also gradually increases. Therefore, optimal installation methods include installing the panel facing the wind at angles of 30° and 45°, or installing it facing away from the wind at a 60° angle, to minimize the impact of wind load on the solar photovoltaic panel.

“…Solar PV systems undergo several losses under real-time operating conditions among that PV module temperature (TPV) loss itself reduces the power generation maximum of 0.65 % per increase in the operating temperature higher than the Standard Test Condition (STC) [2]. Several studies are conducted to cool the excess raise in TPV using sensible and latent heat storage material among these PCM becomes vital in cooling the PV module and extracting the heat energy for thermal applications [3][4][5]. Generally, PCMs are placed behind the PV module using physical or nonphysical contact, as soon as the TPV increases, heat energy transfers to the PCM surface [6,7].…”

Several studies have found that incorporating an appropriate melting temperature (Tmelt) of Phase Change Material (PCM) behind the PV module enhances the cooling effect. In this study, PCM is selected for hybrid cooling for summer and winter using six years of meteorological data obtained from NASA. Considering the hybrid cooling method, winter season Tamb is selected to optimize the Tmelt as the selected PCM must reach the latent heat property in an early sunshine. It is found that during winter, 70 % of the period, Tamb lies around 28 °C whereas the Tmelt of PCM should be in the range of 31-34 °C according to the modified optimization method. In total, twelve combinations of eutectic mixtures are prepared using Lauric Acid (LA), Myristic Acid (MA) and Stearic Acid (SA), and their thermophysical properties are analysed using a differential scanning calorimeter. Only seven eutectic mixtures attain the 31-34 °C Tmelt among that LA:MA (70:30) and LA:SA (70:30) show excellent latent heat of fusion of 194 J/g and 190 J/g, respectively. Furthermore, it is recommended that LA:MA (70:30) and LA:SA (70:30) are suitable for Thailand’s climatic conditions for PV module cooling.
